基于“视频同步互动”的分布式学习专用教室设计与实现

Design and Implementation of Synchronous-Video-Interaction-Based Distributed Learning Classroom

为更好地研究分布式学习，华中师范大学信息化与基础教育均衡发展湖北省协同创新中心探索建设“视频同步互动”分布式学习专用教室：通过异地教师视频影像前端显示、异地教师授课资料前端显示、异地学生听课影像后端大屏幕显示、声音在教室内全覆盖同步互传等技术和工艺方法改进措施，将两地之间的学生通过网络技术融为一体，开展正常的课堂教学活动，实现了真正意义上的分布式学习。

In order to better research distributed learning， CCNU Information and Balanced Development of Basic Education Collaborative Innovation Center in Hubei Province has explored into the building of the synchronous-video-interaction-based distributed learning classroom. Aiming to integrate the students in two different places through network technology， carry out normal classroom teaching activities and achieve the real-sense distributed learning， the following measures are taken through synchronous mutual transmission technologies and applications: display remote teacher’s video images and teaching information in the front of the classroom， display remote students’ video images on a back-end large screen， achieve a full coverage of sound pickup and synchronous transmission in the classroom.
